CARBURETOR.

SPECIFICATION forming part of Letters .Patent No. 488,881, dated December 27, 1892.

. to enrich natural gas by supplying it with sufficient hydrocarbon to render the gas fit for illuminating purposes.

The invention is an improvement in the class of carburetors in which the gas or air to be carbureted, t'. e. enriched with carbon, is directed over the surface of the oarbureting liquid or through perforated absorbent partitions saturated with such liquid. We have devised an improved construction of the carbureting vessel in which the gas enters at the top of the casing, passes downward,and then up through a perforatedl plate, and through the body of the liquid hydrocarbon employed as the carbureting liquid, to the outlet at the top.

The invention is embodied in the construction and combination of parts, as hereinafter specified.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the gures.

Figure 1 is a front view of the improvement; Fig. 2 is a side elevation of the same; Fig. 3 is a transverse section of the same on the line 3-3 of Figs. 2 and 4; Fig. 4 is a longitudinal section of the same on the line 4-4 of Figs. 1 and 3-5 and Fig. 5 is a plan view of part of the perforated plate.

The improved carburetor isprovided with a casing A made in two sections B and C jointed together by iianges D, bolt-ed or otherwise fastened, the said joint extending preferably at an angle of forty-five degrees, as plainly shown in Figs. l and 3. On the under side of the section B are secured or formed legs E for conveniently supporting the apparatus on a suitable foundation.

On the top of the section B is formed an 1892. Serial No. 442,569. (No model.)

inlet F for introducing the necessary liquid hydrocarbon into the apparatus, the said inlet being ordinarily closed by a screw cap or plug. Next to this inlet for the liquid hydrocarbon is arranged a gas inlet Garconnected with the gas supply, so that the natural gas flows into the section B at the upper end thereof. In the bottom of this section B is formed an inclined trough or channel H, provided at its front end with a bib I and serving to draw off sediment or used-up liquid hydrocarbon. The other section C of the casing A, forms a square box J which extends partly into the section B, but does not reach with its lower end close to the bottom of the said section, so thatthe two sections are in communication'with each other at their lower ends. This box J forms on its outside with the section B, the chamber K for the inlet of the gas and also a chamber L, within the box for the outlet of the gas, this chamber being provided at its open bottom with a perforated `plate N attached to annular iianges formed in the inside of the box J, as will be readily understood by reference to Figs. 3 and 4. In the top ofthe section C is arranged an outlet pipe O for carrying off the carbureted gas, it being understood that this pipe opens into the upper end of the gas discharge chamber L. At the sides of the section C are arranged gage cocks P and P', located one above the other and serving to indicate the level of the liquid hydrocarbon within the casing.

The operation is as follows: When the sections B and C are fastened together, then the casing is partly filled with the liquid hydrocarbon introduced through the inlet F, the liquid hydrocarbon standing on the same level within the chambers K and L, as the lower end of the box'J is in communication vwith the section B. When the casing has thus been charged with liquid hydrocarbon the inlet F is closed by the screw cap or plug and then natural gas is admitted to the chamber K through the inlet pipe G. The gas passing into this chamber K flows downward and forces the liquid hydrocarbon into the chamber L and passes Iinally through the liquid and at the same time through the perforated plate N held in the lower open end of the said box J. The gas finally rises in the ssv IOO

chamber L and passes from the latter in a carbureted state to the outlet pipe O from which it is led to the burners or to other devices for further use. Now, it will be seen that the natural gas in passing through the perforated plate N is finely divided so as to be in a proper state to uniformly take up the hydrocarbon contained in the liquid, and at the same time the movement of the gas through the liquid agitates the latter so that the said liquid retains its gravity throughout, and consequently the hydrocarbon taken up by the gas is of a uniform quality. It is understood thatthis agitation of the liquid hydrocarbon is of great importance, as the heavier particles usually contained in the liquid hydrocarbon cannot be readily absorbed by the gas passing through the liquid, but when the latter is agitated the heavier particles remain divided, and consequently the passing gas can readily take up the good qualities of the liquid so that the gas is uniformly and thoroughly enriched.

Having thus fully described our invention, We claim as new and desire to secure by Letters Patents- A carburetor casing composed of the two detachable sections B, C, constructed as described, that is to say, the box-like flanged section O, having a gas outlet at the top and an open bottom, and the flanged section B, having a gas inlet at the top and its sides cmbracing a portion of section C, and constituting the bottom and part of the sides of the latter, whereby chambers K and L for gas and carbureting liquid are formed in the respective sections, as shown and described.
